Dynamic RAM Preview Max
Options Preferences, Dynamic RAM Preview Max
What do you normally set for this value? Some percentage of your system RAM or of Max Available? Thanks in advance. -

Tyson – good question. Extremely good question.
Here’s a few parameters to consider and then “mix-it-up” for your own pudding.:
* Firstly – Without a decent enough Frame rate we can’t get an idea of what is happening. Now, for many people who do very simple/quick cuts/edits and few FX-ing and compositing, the minimal on a fast or even less than fast laptop will get ’em through. And at present my option comes in at 128mb. You can check this under your preferences. I’ve had mine up to the full 1000 whack. And there is the limit as to what version of VEgas you have, that will access more than 3gb(?).
* Secondly – What are you setting your Preview “Quality” to? The higher the quality the MORE RAM for Ram Preview you’ll need. Soooo… Less quality Preview gives you more Timeline. More Quality Preview gives you LESS timeline Preview.
* Thirdly – Consider doing pre-renders. I use them and NOW use extensively a script by Gilles aka “Rosebud” that has developed a superb lil script for producing prerends on the fly – love it!
* Fourth(ly?) – Remove and stand down any unnecessary Motion Blur or Track Fx-ing.
What i would like is VEgas to view what I am doing, make an audit of my RAM and CPU and Cache and decide WHAT I can do to get slippery Previews. Almost like an “Automatic” gearbox! Now THAT would be real neat!
But, to date what we have are the the options above. Meaning for me a variation of RAM from 16mb up to the max and adjusting quality, so, there you have it.

Hey thanks. Let me preface with this:
I’ve created several nestable projects (working with stills). Each may have 2 to 5 tracks, some with 3D Alpha Track Motion. I then have a master project with 6 of the nestable projects. I was A|B-ing the tracks with Mute/Unmute (that’s what drove my “Archive” question from yesterday). I notice that the Preview window looks … well, like some inebriated person who’s first learning how to drive a stick shift.
I tried playing around with the Preview Max value. The window itself is set to Preview(Auto) because I thought I read in the manual that’s a good value to use.
I’ve been playing with these values, 128 to 768MB, Preview(…) and can’t seem to get the Preview window to be more … “smooth” (for lack of a better term).
Thanks again.

How big are the stills? What are the dimensions of your project. The stills should be no more than 2x the project dimensions. If you are not zooming, you can even make them match the project dimensions, especially if it’s an HD project. Using multi-megabyte stills is not recommended.
> Each may have 2 to 5 tracks, some with 3D Alpha Track Motion.
3D Track Motion is very processor intensive all on it’s own. Add to that the fact that still images are being resized at the rate of 30fps and you are almost guaranteed stuttering preview.
> I tried playing around with the Preview Max value. The window itself is set to Preview(Auto) because I thought I read in the manual that’s a good value to use.
Yes, but sometimes you need to go down to Draft (Auto) mode depending how the demands of the project and power of the CPU.

You’re confusing the Preview setting with the Dynamic RAM Preview setting which are two different things. Changing the MB will not affect the preview window at all. This is only for RAM preview which is invoked by making a timeline selection and pressing Shift+B. This dynamically renders the timeline selection to RAM for guaranteed smooth playback. The amount of RAM you use for this determines how large a timeline selection you can make.
